Pacemaker cells Cells that can initiate depolarization on their own Automaticity Ability of pacemaker cells to initiate depolarization SA node Location of pacemaker cells in a normal heart; 70-100 action potentials per minute at rest Conduction system Pathway of electrical conduction in the heart AV node Slows impulse conduction to allow for completion of atrial contraction; 40-60 action potentials per minute if SA node fails Purkinje fibers Rapid conduction pathway in the ventricle...

Chapter 11 - Which of the following structures is the primary pacemaker of the heart? a. Ventricular tissue c. Sinoatrial node b. Atrioventricular node d. Purkinje fibers - ANS: C With an intrinsic rate of 60 to 100 beats/min, the sinoatrial node is the primary pacemaker in a healthy heart. The atrioventricular node beats 40 to 60 beats/min. Ventricular tissue must have an electrical impulse to contract. Purkinje fibers beat 15 to 40 beats/min 3. Why do many patients with very hi...

Electrical Activity of the HeartWhat is an action potential? - correct answer Rapid change in the transmembrane potential followed by a return to the resting membrane potential When do changes in transmembrane potential occur? - correct answer During changes in the permeability of the cell membrane to intracellular and extracellular ions Is the duration of APs in cardiac cells shorter or longer than in nerves cells or skeletal/smooth muscle? - correct answer Much longer What is the effe...
